Situated in a Conservation area at the edge of Brook Green in West London, this stunning house was DOS Architects’ first residential refurbishment project in London. Their client lived in one of the houses and, having bought the house next door, decided to appoint DOS Architects to create a design which merged both houses into a single family house. Caught between the borough’s strict Planning constraints and the client’s ambitious aim to create a bright, spacious and modern house, DOS chose to delimit themselves by retaining the overall structure of the existing house, whilst playing with the potential of a new rear garden extension. The new volume arose as a natural continuation of the house’s existing geometry, allowing the Architects to play with material contrasts to create a delightful transition between outdoor and indoor spaces. The ground and basement floors are linked through the introduction of a double height void which connects the kitchen and dining room to the remaining public areas within the house. The glass box is flanked by a cantilevered shear wall, which serves to realign the house on a north-south axis whilst also creating a bookend to the building.
